T12 Fluorescent Light Bulbs
T12 fluorescent light bulbs are an older type of fluorescent that is still used in many light fixtures today. It's a 1.5 inch diameter light which operates most commonly on magnetic ballasts. It has been the standard for fluorescent lighting, but has often been retrofitted to more energy efficient types like T8 or T5. Many offices and businesses still rely on these to provide dependable, adequate illumination. It comes in many different colors and sizes, everything from color correct to the common cool white version, all providing reliable illumination for almost any lighting task.
